Description
Ayano Nakakouji is a young woman of nineteen years who serves as the heiress to the secluded Nakakouji estate, a position that defines her existence within the shadowed halls of a remote mansion. Her physical presence is delicate and small in stature, with records noting her height as approximately 147 to 150 centimeters and her weight as between 36 and 39 kilograms. She possesses vivid orange or long, waist-length blonde hair typically styled with blunt bangs and curly strands, often adorned with a ribbon or hairband, and her brown eyes can appear yellow in certain depictions.

The lingering grief over her father's death fuels a significant emotional instability in Ayano, leading to erratic shifts in her behavior that range from childlike playfulness to moments of despondent withdrawal. This fragile psychological state makes her the delicate centerpiece of the estate, where the hushed corridors simmer with unspoken tensions among the inhabitants, each seemingly tethered to her precarious emotional gravity. Her daily life is intertwined with the watchful care of the butler Shibata, the academic guidance of her private tutor Kaoru, and the attentive service of the live-in maid Nozomi, alongside the groundskeeper Imada.

As events unfold, Ayano develops a deep psychological fixation on a private detective named Kido, who is employed by her wealthy family for protection. She becomes convinced that Kido is the reincarnation of her former master, a belief that drives her to actively seek becoming his lust puppet, motivated by a desire for submission that is intertwined with a perverted form of devotion. This intense conviction fuels her possessive tendencies and instability, manifesting as intense jealousy toward other women in the household, particularly the maid Nozomi and Kido's own partner, Mei. A notable aspect of her behavior includes her tendency to address Kido as father, though the specific reason for this form of address is not elaborated upon. No notable abilities are documented in the available information.
